Web: Viewing Port Status and Configuring Port Parameters

In the web browser interface:

1.Click on the Configuration tab.

2.Click on Port Configuration.

3.Select the ports you want to modify and click on Modify Selected Ports.

4.After you make the desired changes, click on Apply Settings.

Note that the web browser interface displays an existing port trunk group. However, to configure a port trunk group, you must use the CLI or the menu interface. For more on this topic, see Chapter 12, “Port Trunking” .

The Maximum Transmission Unit (MTU) is the maximum size IP packet the switch can receive for Layer 2 packets inbound on a port. The switch drops any inbound packets larger than the MTU allowed on the port. On ports operating at 10 Mbps or 100 Mbps, the MTU is fixed at 1522 bytes. However, ports operating at 1 Gbps or 10 Gbps speeds accept forward packets of up to 9220 bytes (including four bytes for a VLAN tag) when configured for jumbo traffic. In the 2800 switches you can enable inbound jumbo packets on a per- VLAN basis. That is, on a VLAN configured for jumbo traffic, all ports belong­ ing to that VLAN and operating at 1 Gbps or 10 Gbps allow inbound jumbo packets of up to 9220 bytes. (Regardless of the mode configured on a given jumbo-enabled port, if the port is operating at only 10 Mbps or 100 Mbps, only packets that do not exceed 1522 bytes are allowed inbound on that port.)
